It may look hand drawn, but this work is actually 3d! poser programs have a function by which you can render a sketch version of whatever 3d work you have up in the program at the time. In the regular version, there are 3 3d wolves one next to the other. And by using the sketch render function this came out. It's been sitting on my HD for years, and thought it was time to share it with everyone. I was really surprised at how it came out when I first rendered it this way. Enjoy!
